Let’s go row by row and count the tally marks.
Remember:
Each group of 5 is shown as four vertical lines with one diagonal line crossing them.
Any extra lines after that are just single vertical lines.

Row 1:
Three groups of 5 → 5 + 5 + 5 =
15
Row 2:
One group of 5, plus two singles → 5 + 2 =
7
Row 3:
Just three single lines →
3
Row 4:
Four groups of 5 → 5 + 5 + 5 + 5 =
20
Row 5:
Two groups of 5, plus two singles → 5 + 5 + 2 =
12
Row 6:
Two groups of 5, plus four singles → 5 + 5 + 4 =
14
Row 7:
Two groups of 5, plus four singles → 5 + 5 + 4 =
14
Row 8:
